Determinación de las condiciones de vitrificación del sistema de BaO-TiO₂-Nb₅, con adiciones de AI₂O₃ y B₂O₃, para la generación de precursores dieléctricos
Published 2015“…Para la caracterización del vidrio y la posterior caracterización del vitrocerámico se utilizaron las técnicas de DRX, ATD y espectroscopia de impedancia, cuyos datos obtenidos se utilizaron para obtener un vidrio estable y someterlo a un tratamiento térmico adecuado para la producción y el control de la cristalización del vitrocerámico, así como también para determinar las fases cristalinas presentes. Conclusiones y contribuciones: Se obtuvieron vidrios estables en el rango de composición (en% peso) 50BaO-25Nb2O3-25TiO2 con adiciones del 5, 10, 15 y 20% en peso de B2O3, mediante un tratamiento térmico a 1450°C por 2 horas para producir un material homogéneo, dado que se obtuvieron vidrio estables solo con la adición de B2O3 se optó por omitir el Al2O3. …”
